Yeah, looks like the connect 3 that we had too

You can get the code from nissan for about £20.

We got ours a week before the lockdown. First week was over 500 miles, now it just turned 1000 miles.

On other cars where the dash rattles wouldn't be found, small self adhesive pads in hidden locations worked to do the same as pressing the dash a certain way.

Normal for newer cars. It'll be guessing your range based on recent driving patterns. So a couple of full tank runs on the motorway would give a higher figure at filling.

The diesel would be anywhere from 450 to 650 when filling depending on the driving.

Not really, sticky brakes might be another option

Most local factors can get you the right ones from the reg number. Or go to nissan if feeling a bit richer.

I always thought the nissan/reault diesel sounded like a bags of spanners was thrown into the engine compared to citroen diesel I have. In fact the citroen engine sounds very nice for a diesel.

No, they do it for legal reasons, the speedo will always read high. It means that if it says 50mph and you are in a 50 zone then you can never blame them for speeding. All manufacturers make the speed read slightly high. Normally they quote 10% error, in reality that means from 0 to 10% higher than ...

I would suspect they have a common loom, maybe just the tekna is different.

Only way to know for sure is to look at the connectors on the headunit.
